But what would make a witches tit cold if not for the brass bra?
Phil, I never met a witch except on Halloween, and I for sure never got close enough to determine what kind of bra she was wearing <g>. You apparently are a man of experience (perhaps from your fraternity party days?) and I am sure you will give us an explanation of the question that you have posed.
However, if I was to speculate, the cold analogy would have to do with a "cold" personality, but BWDIK? C'mon, please give us the answer <vbg>.
